Packing for cruises depends greatly on your intended ports of call: the Tahitian islands call for a different wardrobe than the Aleutians. Back on board, the dress code on most lines can be described as country-club casual, with a few "formal" events thrown in. One advantage of cruising is that you only unpack once so, you are free to bring more than you might on a land journey. Prepare for wind and spray on deck with wind-defying and waterproof garments; on-shore explorations call for versatile walking clothes, and remember something a little dressy for evenings at the captains table.
